That is a good idea, Bevziibubble. I was just reading somewhere that you can use frozen grapes in drinks instead of ice cubes so your drink cools without watering it down. People do that with wine. It should work for ice tea too, right.
That batch of grapes I had is gone now. I ended up bringing some over to a friend to share before they went bad. I had thought about throwing them into a smoothie or making juice but I am not really supposed to eat too much fruit all at once because of my blood sugar. The grocery store had the grapes in prebagged packages and there were just too many!
